Impact of wall slip and jump in the heat transmission enhancement of copper-alumina/water hybrid nanofluid due to a stretched cylinder

Abstract

The early jump in wall temperature and partial slip all along transfer on thermal energy in hybrid nanofluid was studied simultaneously. In addition, the flow characteristics and heat transfer performances on alumina–copper/water ($A{l}_2{O}_3-\mathrm{Cu}/H_{2}O$) hybrid nanofluid through the stretching cylinder were examined below the effect on thermal radiation and Lorentz magnetic forces. This Roseland’s flux model was working on the effect on thermal radiations. Denoting fundamental equations was traced over constructing numerical model results about temperature and velocity distributions although considering variable internal energy and fluid property change. The numerical algorithm bvp4c technique was utilised to obtain convergent solutions. The effect on impending parameters of temperature and velocity distributions was investigated over a graphical illustration. It was noticedthat wall momentum diffused with nanofluid quickly to its dispersion on hybrid nanofluid by the existence of the partial slip. The thermal behaviour of the hybrid mono-nanofluid was higher than that of the nanofluid. Moreover, hybrid particles advance the thermal behaviour of the employing fluid.
